不同品种油葵的土壤适应性研究

本文运用DTOPSIS法和灰色关联度法对5个油葵品种在3种类型土壤上的种植表现进行了综合分析.结果表明,5个油葵品种表现为：在褐土上,S606〉T012 244〉S625〉MAT414〉矮大头518;草甸土上,T012 244〉MAT414〉S606、S625〉矮大头518;水稻土上,S625、MAT414〉矮大头518、S606〉T012244.这两种综合评价方法的评判结果基本相同,并与品种实际表现相符.但灰色关联度评价结果中品种间差异不大,而DTOPSIS法评价结果中Ci值差异十分明显,说明在品种比较评价的优劣上,DTOPSIS法比灰色关联度法更加准确。

Studies on Soil Suitability of Different Varieties of Oil Sunflower

By DTOPSIS and Gray Relation Analysis(GRA),we deal with the comprehensive evaluation of the performances with five types of oil sunflowers cultivated in three types of soil.The results show that three different sequencings,such as in Brown Soil,S606>T012 244>S625>MAT414>Aidatou 518;in Meadow Soil,T012 244>MAT414>S606、S625>Aidatou 518;in Paddy Soil,S625,MAT414>Aidato 518,S606>T012 244.Comprehensive evaluation results with the two evaluation method are basically same,and are compatible with the actual performances.However,the discrepancy of Ci Value shows that the evaluation results of DTOPSIS is more evident than that of GRA,which can help illustrate that,on comparative evaluation of the quality different among cultivated varieties,DTOPSIS is more accurate than Gray Relation Analysis.
